UNITED STATES PATENT QFFICEQ J. PALMER, OF CLEVELAND, OHIO.

Specification forming part of Letters Patent No. 5 1,857, dated January2, 1866.

To all whom it may concern.-

Be it known that I, J .PALMER, of Cleveland, in the county of Ouyahogaand State of Ohio, have invented a new and useful Improvement in theManufacture of Sand-Paper and I do hereby declare that the followingisafull, clear, and exact description thereof, which will enaable othersskilled in the art to fully understand and make use of the same.

This invention consists in the application, to common sand, flint, oremery paper, of boiled linseed-oil or other equivalent fatty substance,in such a manner that after the paper has absorbed the oil, and said oilhas become thoroughly dry and fixed in the pores of the paper, anarticle is obtained of much greater toughness and firmness thansand-paper made in the usual manner, and mysand, flint, or emery paperis more durable and economical than any other similar 'article.

In carrying out my invention I take sand, flint, or emery paper made inthe usual manner, or I prepare such paper as usual, and after the sand,flint, or emery has been applied to the surface of the sheets and thesheets have been thoroughly dried I apply to their backs boiledlinseed-oil or other quick-drying fatty substance in such quantity asthe fibers of the paper will absorb. The oil or fatty substance may beapplied by hand or bysuitable machinery, and after the sheets aresaturated therewith they are left to dry. The oil penetrates the fibersof the paper and renders the same tough and tenacious, and paperprepared according to my process is much more durable, and consequentlymore economical in its use, than sand, emery, or flint paper prepared inthe ordinary manner and Without the application of fatty substance.

What I claim as new, and desire to secure by Letters Patent, is-

Sand, flint, or emery paper saturated with boiled linseed-oil or otherquick-drying fatty substance, as a new article of manufacture.
